To tackle this, a flow-land-infrastructure-petrochemical (FLIP) multi-factor model is developed with integration of material and energy flow analysis and decoupling assessment, targeting industrial carbon peaking via industrial structure upgrading and production efficiency improvement of four-digit level petrochemical sub-sectors. A nationally leading petrochemical industrial park was then selected to validate the model's effectiveness and robustness. Through the model optimization, the park could achieve 19 % and 30 % of CO<sub>2</sub>e emission reductions in 2025 and 2030 respectively, compared with emissions in the scenario without intervention. The overall carbon productivity could rise by 89 % with a decoupling index of -0.15 between economic growth and carbon emissions during 2020–2030, showing a feasible carbon peaking pathway. Infrastructure with lock-in emissions needs energy system transformation and adjacent industrial symbiosis from a regional perspective, while promotion targets and entry thresholds of carbon productivity should be individually tailored for each stock and incremental manufacturing sub-industry. The model could be extended to other petrochemical clusters and emission-intensive industries, synergistically addressing the effects of structure upgrading and efficiency progress to support practical and economically sustainable carbon peaking pathway formulation.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"24 ","pages":"Article 200236"},"PeriodicalIF":5.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study highlights how the community effectively addressed a significant waste problem that was negatively impacting water sources and causing pollution. The leadership of the community leader played a crucial role in implementing successful strategies, including developing diverse participation approaches to meet the needs of various community members. The community utilized the PDCA (Plan Do Check Act) cycle to drive progress, and the task force operated on a foundation of equality, fostering horizontal relationships, and distribute of incentives. The process of effecting change was described in line with the theory of change, resulting in a successful outcome.

This paper presents a systematic review of theories and models applied to understanding SCB. A total of 64 studies, published between 2012 and 2022, were analyzed, utilizing 14 theories, models and subjects to identify key drivers of SCB. Among the theories, the Theory of Planned Behavior (TPB) was the most frequently employed, with 29 studies, highlighting the influence of attitudes, subjective norms, and perceived behavioral control on sustainable consumption. Other prominent frameworks include Social Cognitive Theory (SCT), used in 5 studies, and the Value-Belief-Norm (VBN) Theory, applied in 4 studies. The review identified a trend toward expanding TPB to include factors such as altruism and environmental concern to better capture SCB's complexity. Moreover, models like the Diffusion of Innovation Theory (used in 4 studies) emphasize the role of innovation adoption in promoting sustainability. Key findings also suggest that while internal motivations (e.g., personal values, attitudes) strongly influence SCB, external factors like social norms and policy interventions also play a crucial role. A notable challenge is the gap between intention and actual behavior, with several studies emphasizing the need for multi-dimensional approaches that integrate psychological, social, and contextual factors. This review consolidates diverse approaches into a guiding framework for future SCB studies, emphasizing the importance of contextual nuances and interdisciplinary collaboration to foster sustainable consumer behaviors across various domains.</div></div>","PeriodicalId":74689,"journal":{"name":"Resources, conservation & recycling advances","volume":"23 ","pages":"Article 200232"},"PeriodicalIF":5.4,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142441732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
